What's the name of this tv show?

K-9 (TV series). K-9 is set in near-future London, with 14-year old characters Starkey and Jorjie, alongside a Professor Gryffen, who is experimenting with a Space-Time Manipulator, and an "artful dodger" 15-year-old Darius who runs errands for Gryffen. K-9 Mark I follows the villainous reptilian warrior Jixen who come through a space-time portal created by the professor's experiments and saves the Londoners. While protecting them, K-9 is forced to self-destruct, but is able to give Starkey instructions to rebuild and regenerate himself into a more advanced form. K-9 and the humans then form the front line defence against alien menaces from outer space and other times.[23] The Brisbane Times reports that the series is set in London in the year 2050 and Professor Gryffen is employed by a clandestine government agency, "The Department".[18] The design of K-9 is noticeably different from that seen in Doctor Who because although Bob Baker owns the character rights to K-9, the original character design is owned by the BBC.
